Yariv Oppenheimer, secretary general of the left-wing Peace Now movement, announced on Monday that he would run for a spot on the Labor Party list in the party’s November 27 primary elections.

Promising to promote a political agenda alongside the social and economic agendas being advanced by other new Labor candidates, Oppenheimer announced that he would leave the position that he has held in Peace Now since 2003. This will be the third time that Oppenheimer has attempted to gain a seat with the Labor Party. In both 2006 and 2009 he failed to secure a realistic spot on the party list.

Oppenheimer, 35, pledged to continue the efforts that he has promoted as the head of Peace Now — “to bring a clear political agenda that advocates a two-state solution and ending the huge investments in the settlements.”

In recent weeks, the Labor Party has welcomed several high-profile additions to its ranks, including venture capitalist Erel Margalit, journalist Mickey Rosenthal, and social protest leaders Stav Shaffir and National Union of Israeli Students chairman Itzik Shmuli.

The general elections are to be held January 22, 2013.
